PAUL JOSEPH LEMATTRE, OF ABBEVILLE, FRANCE.

elates to an apparatus for the hydraulic unloading of beets from carscarrying the same,

into the trench which is situate along the railwaytrack.

In a known process a stream of water under pressure from a hose is usedby the workmen to expel the beets from the car into the side trench, butthis method has many drawbacks and requires a complicated mechanism.

In my invention,

use is made of a main water pipe disposed above the track at a muchhigher level than the platform of the car, and in this manner a water iscaused great quantity of to descend, without pressure, upon the beets,whereby the car can be rapidly cleared age to the beets.

out and without any dam- Obviously, the water pipe is provided withsuitable valves for the flooding or for stopping the water, and alsowithsuitable branch conduits of large size upon which the valve can beopened in each case in order to various cars.

The invention supply the water to the relates to an apparatus which isso constructed and disposed that a single person can operate it so as tosend the water successively upon all the different parts of for a car ofgreat length,

the surface of the car,

and even and in this manner the device is very rapidly operated. Theinvention consists essentially in the use of a large shape, inclinedreference to a di tube which has preferably a tapered of suitablelength; said tube can be by an irreversible mechanism with so revolubleon a vertical axis about the conduit of the main water tube.

The appended drawing shows by way of of Fig. 1.

Fig. 3 is a top view of the apparatus.

A neck 1 of large diameter is connected the inte through shown, with themain raised water pipe,

valve, not

rmediary of a and it replaces or forms the head of the usual conduit.The sai firmly attached thereto,

eting, a sleeve 2 serves as a support the revoluble disc d largediameter neck has for exampleby rivwith wide flange 3 which and as aroller path for L; the rolling balls 4' are preferably interposedbetween the members 3 and 4 so as to of said disc on th facilitate therotation e vertical axis of the neck.

23', Serial No. 615,289, and in France February 4, 1922.

The said disc has secured thereto a sheet metal feeding conduit or waterjet tube 5 which has preferably a tapered shape, this being suspendedfrom the disc 4i on the axis X'Y; on one side, for example, the .saidconduit is suspended by a pin or shaft 6 attached to a flange on saiddisc and extending through a hole in the upper part of said conduit. Onthe other side a shaft 7 rotates in two bearings 8 and 8' secured to thedisc 4, and the upper part 5 of the conduit 5 is keyed to the shaft 7 soas to rotate together with the latter.

On the shaft 7 is mounted a worm wheel 9 actuated by a worm 10 which isjournaled in bearings 11 secured to revoluble disc 4L, said worm beingcontrolled by the hand wheel 12. In this manner, by turning the saidhand wheel, the worm wheel 9 will turn through a certain angle, thuscausing the conduit 5 to take an inclined position as shown in thedotted lines, Fig. 1. The shaft 13 is given a suitable length betweenthe hand wheel and the worm, and thus the workman stationed upon anoperating latform surrounding the water discharge tube is enabled toperform the following operations with facility; flrstly, he controls thevalve for opening and closing the water supply, secondly, he can pushthe hand wheel to one side, using the shaft 13 as a lever, and is thusenabled to turn the conduit 5 about the vertical axis by reason of theball bearing arrangement, thirdly, by turning the said worm he mayincline the feed conduit so as to send the water stream to the ends ofthe car, and even when inclined, the said conduit will not bring anyweight upon the operator owing to the irreversible control obtained bythe worm gearing, and the Workman can thus leave the feed conduit in theinclined position for the whole time necessary to clear out the end ofthe car.

It is ascertained that a device of this kind can be used by a singleoperator to discharge some 2000 tons of beets per day.

Claims:

1. An apparatus for the hydrauiic unloading of material from vehiclesinto a lateral storage space, comprising a substantially vertical andstationary Water inlet branch, a horizontal support turning coaxiallyabout said inlet branch, a water jet tube the upper part whereof ismounted upon said support and is spaced from and oscillates, about saidinlet: branch, whereby the Water jet tube may oscillate about ahorizontal axis passing through said inlet branch and in any position:receive the wa ter escaping freely from the inlet branch,

andco-mmon means tooscillatesaid waterjet tube about a horizontal, axisand to r0- tate same about a vertical axis.

2. An apparatus, of the character described adapted. for connection to.a. raised Water supply, said apparatus comprising a Water inlet branchhaving a supporting member seeurecl thereabout, an intermediate memleer,carried by said supporting member for retative; mewement, saidintermediate member having flanges thereon, a water jet tube havingflanges thereon, pivot pins passing tlirenglm recesses respeetiwely inflanges of the intermediate member and Water jet tube, whereby to securesaid water jet tube to the intermediate member, and means [carried bysaid intermediate member toincline the Water jet tube, with respect tothe horizontal and hold it in any one of its inclined positions.
